Hallo,
it seems to me that Score DSV does not satisfy
monotonicity. It seems to me that the following
scenario is possible:
Candidate A is the original winner.
Suppose some voters rank candidate A higher
without changing the order in which they
rank the other candidates relatively to
each other. Then it is possible that some
other candidate B is kicked out of the Smith
set and that, after renormalizing the ballots,
candidate A is worse off.
